I wouldn't know why it does this, but a highly likely explanation is 
that the installers dlopen() C:\WINDOWS\DDRAW.DLL using an absolute or 
semi-absolute (flexible Windows directory, in case Windows is installed 
on D: or even in "D:\WINNT\") path. It probably also tries to stat() 
thew file before opening it so that the lack of the file causes an error 
before it is dlopen()d.

A good suggestion is if a DLL file is stat()d in the 
c:\windows\system(32) directory in Wine, Wine should check it against 
any .so files in $INSTALLPREFIX/lib/wine, and claim the file exist if a 
compatable .dll.so is found. Wine should also 'remember' this mapping in 
case of fopen() or compatable calls.
